Owning your own home

As long as you have an appropriate fuse in the plug. Not sure what that would be but guessing 3 or 6 amp. Otherwise the cable could heat up and catch fire (this is very unlikely to ever happen!).

Heals have them in their shop (or used to, haven't been past in a while)

the cable linked to is not suitable for:

fixed wiring inside containment
fixed wiring buried
non-double insulated (class2) appliances

it is suitable for:

low current final connections to appliances where some movement is expected (e.g. lamp pendants), that are double insulated (class2)
